  833. # interfaces). Other BSSIDs can be added by using separator 'bss' with
  834. # default interface name to be allocated for the data packets of the new BSS.
  835. #
  836. # hostapd will generate BSSID mask based on the BSSIDs that are
  837. # configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
  838. # not the case, the MAC address of the radio must be changed before starting
  839. # hostapd (ifconfig wlan0 hw ether <MAC addr>).
  840. #
  841. # BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
  842. # specified using the 'bssid' parameter.
  843. # If an explicit BSSID is specified, it must be chosen such that it:
  844. # - results in a valid MASK that covers it and the dev_addr
  845. # - is not the same as the MAC address of the radio
  846. # - is not the same as any other explicitly specified BSSID
  847. #
  848. # Please note that hostapd uses some of the values configured for the first BSS
